You should go over each line segment exactly once.

I just know the very much basics of graph theory, so I did it with common sense. But it seems to be a trail of the graph. Siddharth Kumar · 3 years, 7 months ago

We'll have to find if it is an Eulerian Graph Agnishom Chattopadhyay · 3 years, 7 months ago

@Agnishom Chattopadhyay Keep it simple, Agni. Sometimes our minds overthink or jump to conclusions. I'm sure it's not completely necessary to use the Eulerian graph method. Gaurav Simha · 3 years, 7 months ago

Note that we must start on a vertex with an odd number degree, otherwise it cannot be done. Therefore, we start at the vertex on top of the brown base. After starting there, any path will eventually take you to a complete path, given that you don't get to the tip of the tree (because the tip also has odd degree) before going to all the other places.
